Abstract
Description
Technical Field
[0001] This utility model relates to the field of cantilever lifting equipment technology, specifically to an auxiliary support structure for the outriggers of a lifting equipment. Background Technology
[0002] Due to their unique structure and high operational flexibility, cantilever cranes are widely used in construction site loading and unloading, warehouse hoisting, and ship-shore operations. Most existing cantilever crane outrigger structures use rigid struts to directly support the ground, relying on ground friction and gravity to suppress the hoisting reaction force. In actual operation, the ground is often uneven or soft, and a single support structure cannot provide sufficient lateral stability. Especially when the boom of a single cantilever crane swings significantly or is lifted under heavy load, it is more likely to cause torque deviation or side slippage.
[0003] Based on this, the present invention designs an auxiliary support structure for the outriggers of lifting equipment to solve the above problems. Summary of the Invention
[0004] The purpose of this utility model is to provide an auxiliary support structure for the outriggers of lifting equipment to solve the above-mentioned technical problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary support structure for the outriggers of a lifting equipment, comprising: an outrigger rod and a crossbeam arm; two symmetrical limiting plates are fixedly connected to the outer wall of the outrigger rod, a rotating ring is rotatably arranged between the two limiting plates, two symmetrical connecting columns are fixedly connected to the outer wall of the rotating ring, a joint is fixedly connected to one end of each connecting column, a hanging hole is opened at one end of the joint, and a self-locking hook is hung in the hanging hole, a steel rope is fixedly connected to one end of the self-locking hook, and a first base plate is fixedly connected to the other end of the steel rope;
[0006] One end of the outrigger rod is fixedly connected to a second base plate, and a side support plate is fixedly connected between the second base plate and the outrigger rod. Pile nail holes are opened on the outer walls of both the second base plate and the first base plate.
[0007] Preferably, a baffle is fixed to the outer wall of the connecting column, and the baffle is disposed on the outside of the connection position between the connecting column and the joint to limit the slippage of the steel rope.
[0008] Preferably, the steel rope is led out by a self-locking hook, wound around the connecting post between the baffle and the swivel, and extends outward to be fixedly connected to the first base plate, thereby allowing for adjustment of the required length.
[0009] Preferably, the swivel ring is sleeved between the two limiting plates and can rotate around the axial direction of the support rod.
[0010] Preferably, one end of the crossbeam arm is rotatably connected to the end of the outrigger rod away from the first seat plate via a hinge, for connection with the crane body, providing lateral path and support.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] Two steel cables connect the first base plate and the swivel simultaneously. After the first base plate is fixed, it achieves flexible compensation for the lateral tension of the outrigger rod. After the second base plate is fixed, they cooperate with each other to improve the stability and prevent torque deviation or side slippage. The steel cables can be wrapped around the connecting column to adjust the length. Through the rotatable cooperation of the swivel, it can be used for more support angles and working sites.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4This utility model provides a technical solution: an auxiliary support structure for the outrigger of a lifting equipment, including: an outrigger rod 1 and a crossbeam arm 2; two symmetrical limiting plates 3 are fixedly connected to the outer wall of the outrigger rod 1, a rotating ring 4 is rotatably arranged between the two limiting plates 3, two symmetrical connecting columns 5 are fixedly connected to the outer wall of the rotating ring 4, a connector 7 is fixedly connected to one end of the connecting column 5, a hanging hole is opened at one end of the connector 7, and a self-locking hook 8 is hung in the hanging hole, a steel rope 9 is fixedly connected to one end of the self-locking hook 8, and a first seat plate 10 is fixedly connected to the other end of the steel rope 9;
[0022] One end of the outrigger rod 1 is fixedly connected to a second seat plate 11, and a side support plate 12 is fixedly connected between the second seat plate 11 and the outrigger rod 1. Pile nail holes are opened on the outer walls of the second seat plate 11 and the first seat plate 10.
[0023] Two limiting plates 3 restrict a rotatable swivel ring 4 on the outrigger rod 1. The swivel ring 4 allows personnel to easily adjust the installation angle of the first seat plate 10 at one end of the steel rope 9. The connecting column 5 forms an anchoring structure with the self-locking hook 8 and the steel rope 9 through the joint 7. The self-locking hook 8 is a press-type anti-disengagement hook, which can quickly detach and install the steel rope 9 after pressing, facilitating temporary operations. The other end of the steel rope 9 is then fixed to the ground through the cooperation of the first seat plate 10, thereby increasing the lateral support force of the outrigger rod 1 and preventing tilting or slippage. Both the first seat plate 10 and the second seat plate 11 have pile nail holes, which can be fixed by cooperating with the pre-embedded anchor pile nails in the concrete foundation. One end of the outrigger rod 1 and the second seat plate 11 are further stabilized by the evenly distributed side support plates 12. The multiple integrated structures are compact and suitable for the reinforcement needs of asymmetrical forces on a single cantilever crane.
[0024] More preferably, a baffle 6 is fixed to the outer wall of the connecting column 5. The baffle 6 is located on the outside of the connection position between the connecting column 5 and the joint 7 to limit the slippage of the steel rope 9.
[0025] The baffle 6, as an extension of the connecting post 5, is located at the entry and exit path of the steel rope 9. When the steel rope 9 is wound around the connecting post 5, the baffle 6 restricts its position, prevents it from slipping or accidentally coming off, and improves the stability of the running path of the steel rope 9.
[0026] In a further preferred embodiment, the steel rope 9 is led out from the self-locking hook 8, wound around the connecting post 5 between the baffle 6 and the swivel 4, and extends outward to be fixedly connected to the first base plate 10, thereby adjusting the length required for use;
[0027] The steel rope 9 is wound using the structure of the connecting column 5. The length of the steel rope 9 can be adjusted appropriately by changing the number of winding turns or the angle, providing an adjustable length function to adapt to different support angles or hoisting conditions.
[0028] More preferably, the swivel 4 is sleeved on the support rod 1 between the two limiting plates 3, and can rotate around the axial direction of the support rod 1;
[0029] The swivel 4 and the outrigger form a relative rotation structure. When the steel rope 9 is under force, the swivel 4 can automatically adjust its direction according to the angle, so that the force is more uniform and the steel rope 9 can be arranged at multiple angles, thus enhancing its flexibility and adaptability.
[0030] More preferably, one end of the beam arm 2 is rotatably connected to the end of the outrigger rod 1 away from the first seat plate 10 by a hinge, for connection with the crane body, providing lateral path and support;
[0031] The crossbeam arm 2 adopts a rotatable hinge structure for use in crane installation operations, and can be rotated according to operational requirements.
[0032] One specific application of this embodiment is as follows: After the self-locking hook 8 is attached to the connector 7, the required length is determined by winding the steel rope 9 around the connecting column 5. At the same time, the installation direction and position are adjusted by rotating the swivel 4. After determining the installation position, the second base plate 11 is anchored to the ground by pre-embedded anchor piles in the foundation such as ground concrete. The first base plate 10 is pre-fixed in the same way. After the lifting operation is started, it will provide lateral tension and anti-slip protection instead of relying solely on the single support of the outrigger rod 1.
